The effect of salt precipitation on the petrophysical properties and the adsorption capacity of shale matrix based on the porous structure reconstruction

•Effects of salt precipitation on the properties of the shale matrix are studied.•The 3D porous structure reconstructions of the shale matrix are conducted.•Petrophysical properties are simulated based on the reconstructed pore networks.•The methane adsorption capacities at different temperatures are predicted.•The method complements laboratory measurements or empirical rock property models.
